SPECIFICATION forming part of Letters Application filed December 21, 1886.

Patent No. 359,922, dated March 22, 1887.

Serial No. 222,139. (No model.)

To a-ZZ whom it may concern:

Be it known that I, FRANCIS W. DUNN, o Lisbon township, in the county of W'aukesha, and in the State of lVisconsin, have invented certain new and useful Improvements in Land- Markers; and I do hereby declare that the fol lowing is a full, clear, and exact description thereof.

My invention relates to land-markers; and it consists in certain peculiarities of construc tion and combination of parts, to be hereinafter described with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a plan view of a land-marker constructed in accordance with my invention; Fig. 2, a side elevation of the same; Fig. 3, a detail front view showing the manner ofjoining the wheel-j ournals {to the axle; and Fig. 4, a vertical longitudinal section 011 line co m, Fig. 1.

Referring by letter to the drawings, A represents the wooden aXle of my landmarker, and B the metallic journals for the wheels 0.

The journals 13 are arranged beneath the axle to rest in boxes a and the vertical portions bof angular housings D, bolts 0 c serving to retain said parts in their relative positions, as best illustrated by Fig. 3.

If found desirable, the axle A may be hollowed out at its ends to partially inclose the journals.

Fitted in the angular housings D at the ends of the axle A, and secured to the latter by the bolts 0, are the front ends of rcarwardlyextended inclined side beams, E, preferably constructed of wood, and braced by metallic strips E, having their respective ends bolted to said axle and side beams.

To the rear ends of the beams E are fitted angular plates E through which latter and. said side beams are passed the reduced upper ends, (I, of vertically-depending guides F, that are joined at their bottoms and rest upon the rearwardly-extended arms G of a transverse beam, G, the latter being seated in and bolted to angular hangers A, that are in turn bolted to the axle A. The axle A, side beams, E, vertical guides F, transverse beam G, and angular hangers A constitute the main frame of my machine. The upper ends, (I, of the vertical guides F are screw-threaded to receive nuts 41', between which and the plates E on the side beams, E, are interposed suitable washers, d

Between the vertical guides Rat their lower ends, are arranged angular seats F", securediu position bybolts 6, passed through the vertical portions of the seats, and guides, and ears e on the arms G ofthe beam G.

Operative between the vertical guides is atransverse beam, H, preferably ofwood, having bolted thereto,upon the upper side,slotted metallic plates H, provided with depending wings f, these plates serving to engage and bear upon said guides.

At suitable intervals on the beam H, I secure plates I,perforated at their outer ends to form guides for vertically-disposed anglerods J, on which are arranged springs g, that bear against the under side of said plates, the tension of these springs being regulated by means of nuts 9, operative on the angle-rods.

The lower ends of the rods J are pivotally connected to the bifurcated ends of bolts ii, that pass through vertically-depending hangers J and marking-fingers K, secured in these hangers, the latter being in turn pivotally connected to the cars h of plates J", fastened to the under side of the beam H.

By the construction above described the marking-fingers K are permitted to yield on striking a stone or other obstruction in the path of the machine, the tension ofthe springs g being readily adjusted in accordance to the nature of the land to be operated upon.

The beam H is provided with hooks or eyes 3', to which are connected cords or chains L, that pass up over pulleys L .on a shaft, L", journaled in the rear ends of the inclined braces E, and are finally secured to grooved segments M on a shaft, M, operative in bear ings M, projecting from the axle A, this latter shaft being opera ted by means of a hand-lever, N, provided with a spring-dog, N, to engage a rack-plate, N", that also projects from said axle.

By the construction described in the pre- Operativein hangers P, depending from the over upon the top of said beam, and thusserve to front of the axle A, are the reduced forward ends, 70, oflongitudinal sliding bars Q, provided with collars 7c, between which latter and said bearings springs Q are arranged to exert their force in a rearward direction.

In the rear of the collars k thereon the lonpushed forward, and the expansion of the,

springs Qwill force the bars Q rearward to come hold the latter down in the position described at the beginning of this paragraph.

Before the lever N is operated to raise the beam H, the lever B is drawn back to bring the longitudinal bars Q clear of said beam,thisposition of theparts being best illustrated in Fig. 4.=

Bolted to the tongue S of my machine is a bracket, S, provided with bearings m for a transverse sighting-bar, T, the latter being provided with collars n, to prevent lateral play.

To the turned-down ends T of the sightingbar T, I secure fingers U, and to an ear, n, on said bar I secure one end of a cord or chain, V, that is fastened at its other end to an eye, 0, on the shaft M, that carries the segments M. By the construction just described the fingers U on the sighting-bar T are turned rearward when the lever N is operated to elevate the beam H, carrying the markingfingers K.

The landmarker above described is very simple in its construction and effective in its operation, while at the same time by its usea saving in time and labor will be effected, as but one operator is necessary to a machine, and said operatorrides thereon.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.? In a land-marker, the combinationof a .suitablemain frame, a verticallyadjustable transverse beam carrying a series of depending fingers, and a sightingbar, substantially as set forth.
